Immunohistochemical staining of frozen tissues with chicken anti-human claudin IgG. Normal tissue from human kidney (right panel) was stained with mouse anti-Ep-CAM (3B10) antibody and anti-claudin 3 chicken IgG (CLDN3.3). Human renal carcinoma tissue (left panel) was stained with anti-claudin 3 chicken IgG (CLDN3.2). IgG from a nonimmunized chicken egg served as negative controls. Cell staining was analyzed by phase contrast microscopy.
